By far the easiest way to cause poor performance, instability, overheating and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, or Virus scanners, Bit Torrent, or a VPN that you installed yourself.
you appear to be running Trusteer.
remove that junk right away, and NEVER re-install.
you are also running FAR too many third-party file-syncers.
File providers:
[Loaded] Dropbox - /Applications/Dropbox.app
[Loaded] Google Drive - /Applications/Google Drive.app
Share services:
[Loaded] Dropbox Transfer - /Applications/Dropbox.app
[Loaded] OneNote - /Applications/Microsoft OneNote.app
Third-party file Sync-ers such as DropBox, BackBlaze, OneDrive, or GoogleDrive can ruin performance, and use overheating but are not inherently dangerous.
They were Quickly ported from that other Operating System, and were never re-written to take advantage of the MacOS ‘File System Event Store’. The typical brute-force search they use takes all afternoon for one pass. That relentless searching is a completely un-necessary waste of resources.
Synch and Backup programs like iCloud Drive and Time Machine that DO use the MacOS File System Event Store can find changes really quickly and be done with their work and suspend themselves. Time machine can run backups Hourly, while all those others are still beating on the file system for the first pass, four hours later. By the time those others have finished one pass, they need to start again.
